The author carefully ignores any evidence that runs contrary to his arguments providing a distorted portrayal of Buddhist-Muslim interaction.

Perhaps, Mr. Elverskog could explain us why exactly Muslims did not destroy the Bamiyan Buddhas until the 21st century?

Because they lacked the explosives to carry out the destruction. With smaller sites of Buddhist worship they had no such problems. Just as they had no problem slaughtering the teachers and disciples of Nalanda. The Muslim destruction of Buddhist culture was recorded by a Persian historian, Minhaj-i-Siraj in the e13th century.
